Definitions
- the present invention relates to novel luster pigments based on metal oxide-coated aluminum platelets where the substrate aluminum platelets have a total carbon content ⁇ 0.1% by weight, to a process for preparing these luster pigments, to the use thereof for coloring paints, printing inks, plastics, glasses, ceramic products and decorative cosmetic preparations, and to the aluminum platelets having a total carbon content ⁇ 0.1% by weight for use as intermediates for the pigments of the invention.
- Metal oxide-coated, in particular iron oxide-coated, aluminum pigments are known per se. They usually are platelet-like substrate particles of metallic aluminum, in general with largest diameters of about 1-200 ⁇ m and a thickness of about 0.1-2 ⁇ m, coated with a metal oxide layer.
- the optical effect of these pigments is due to a combination of the properties ascribable to the metallic substrate, such as metallic luster, lightness flop on viewing from different angles and hiding power, and of the color effect caused by the oxide layer. If the oxide layer is a colored layer, for example an iron oxide layer, this color effect is the result of a juxtaposition of the interference color, which depends on the thickness of the oxide layer, and the respective absorption color.
- the applied metal oxide layer is hematite ( ⁇ Fe 2 O 3 )
- a low iron content will result in pigments having a greenish yellow hue which, as the iron content increases (and the oxide layer thickens accordingly), will change via gold, golden red and orange into deep red. Since these pigments are notable primarily for cleanness of hue, high hiding power and high weathering fastness, they are of particular interest for coloring paints, printing inks and plastics.
- prior art metal oxide-coated aluminum pigments have application disadvantages, not least due to the frequently inadequate adhesion of the oxide layer to the metallic substrate.
- the mechanical stress of dispersing in binders will result in the abrasion of the metal oxide and hence in undesirable color changes.
- gas evolution and, on prolonged storage, hue shifts are observed even in aqueous binder systems.
- the pigments thus obtainable have the above mentioned disadvantages; secondly, pigments having the same chromaticity coordinates, in particular the same chroma (C* of the CIELAB system), are difficult to prepare reproducibly.
- a further problem with the aqueous processes as described for example in JP-A-81 337/1979 and 130 375/1986 is that the aluminum particles react during the coating step with the evolution of hydrogen. It is also necessary to maintain certain reaction conditions, for example a certain pH, and to use costly ancillaries, for example complexing agents. And, after coating, the pigments have to be isolated in a costly manner.
- the luster pigments of the invention are notable for the fact that their metallic substrates have a low total carbon content of ⁇ 0.1% by weight, preferably ⁇ 0.05% by weight, particularly preferably 0.04% by weight. There is in principle no lower limit for the carbon content. The only essential requirement for achieving the desired properties is that the upper limit of 0.1% by weight must not be exceeded. In general, the aluminum platelets will have a total carbon content within the range from about 0.01 to 0.1% by weight.
- the total carbon content is in effect a measure of the level of organic impurities in the aluminum platelets.
- organic impurities are in general lubricants such as oleic or stearic acid and fatty amines which are customarily used in the production of the aluminum platelets by grinding to prevent any cold welding of the platelets. This is in fact the only inexpensive way of obtaining the desired thin platelets ⁇ 1 ⁇ m in thickness. As processed these aluminum platelets thus have a residual carbon content of about 0.6-1.5% by weight. This carbon content is also present in aluminum platelets produced by grinding in an organic solvent such as naphtha.
- the aluminum platelets are not subjected to any special cleaning or purification.
- conventional methods such as washing with organic solvents and/or drying under reduced pressure at elevated temperatures are in general not able to reduce the total carbon content to below 0.5% by weight, which is why the pigments exhibit the above mentioned disadvantages after coating.
- the metal oxide layer can be composed of the highly refractive, colorless or colored metal oxides or mixtures thereof customarily used for producing luster pigments.
- preferred oxides are titanium oxide, zirconium oxide, tin oxide and chromium oxide. Because of the resulting color effects there is a particular preference for iron oxide, in particular ⁇ -Fe 2 O 3 .
- an additional metal oxide may be applied in the form of a preferably colorless top coat. Suitable for this coating are for example silicon oxide and aluminum oxide or hydroxide as well as the colorless metal oxides mentioned earlier.
- the luster pigments of the invention are brilliant and strong in color, their chroma being 15 units higher than that of prior art pigments. Moreover, they have a firmly adhering metal oxide coat and show an appreciably better constancy of hue when stored in aqueous and nonaqueous binder systems.
- the luster pigments can be prepared with advantage by the process of the invention by subjecting aluminum platelets obtained using the above-described, conventional method which aluminum platelets have a total carbon content >0.5% by weight, initially in a first step a) to a cleaning or purifying operation and then in a second step b) to a conventional coating with metal oxide.
- the process of the invention is preferably carried out in a fluidized bed reactor in which the aluminum particles are fluidized by means of an inert gas such as argon or in particular nitrogen and into which the respective treatment gases are blown and thus come to envelop the metal particles.
- an inert gas such as argon or in particular nitrogen
- the purifying/cleaning step a can also be carried out in a different apparatus which permits through mixing, for example in a rotary flask.
- step a) the aluminum particles are treated at elevated temperature with an oxygen-containing gas and if desired additionally with steam.
- the process conditions are advantageously chosen in such a way that the aluminum particles do not ignite.
- the reaction temperature is therefore in general from 150° to 270° C., preferably from 180° to 220° C.
- the oxygen-containing gas used is preferably a mixture having an oxygen content of from 1 to 5% by volume, in particular from 2 to 4% by volume. Particular preference is given to air/nitrogen mixtures of the right composition. If the preferred fluidized bed reactor is used, sufficient air is blown in for the mixture of fluidizing gas and air to have the abovementioned oxygen content.
- the oxidizing treatment generally takes from 2 to 12 h.
- the steam treatment generally takes from 0.5 to 1 h.
- the overall treatment is carried on until the desired carbon content of less than 0.1% by weight is reached.
- the effect is to remove from the aluminum surface not only physically but also chemically attached organic impurities.
- the resulting low-fat, hydrophilic surface is highly suitable for depositing metal oxide layers which will adhere firmly.
- step b The subsequent coating with metal oxide (step b) is carried out in a conventional manner by gas phase decomposition of volatile compounds of the metals using oxygen and/or steam, as described for example in EP-A-33 457, preferably likewise in a fluidized bed reactor.
- the purified/cleaned aluminum substrate thus does not have to be first discharged, but can advantageously be coated directly in the same reactor, if necessary after it has cooled to the desired reaction temperature.
- a desired additional metal oxide top coat can likewise be applied directly following the first coat, for example with iron oxide.
- Suitable metal compounds are the compounds usually used for this purpose and described for example in the earlier German Patent Application P 42 17 511.9 such as the carbonyls, halides, in particular chlorides, and alkoxides.
- Specific examples are titanium tetrachloride, zirconium tetrachloride, silicon tetrachloride, tin tetrachloride, aluminum chloride, titanium n-isopropoxide, titanium isopropoxide, chromium hexacarbonyl and preferably iron pentacarbonyl.
- the carbonyls are advantageously oxidized with oxygen mixed with nitrogen, while the halides and alkoxides are hydrolyzed with steam, although in the case of the halides oxygen can be present.
- the process of the invention makes it possible to prepare the advantageous luster pigments having low carbon contents in a simple manner and--regardless of the particular aluminum batch used--reproducibly. Moreover, the process of the invention ensures uniform coating of virtually all substrate particles (in general 98-99% of the particles). No agglomeration of the pigment particles is observed; if, for example, an aluminum pigment having the total carbon content of 0.04% by weight required by the invention and an average particle diameter of 13.8 ⁇ m is coated with Fe 2 O 3 until a yellowish golden color is obtained, then the average particle diameter only increases to 15.1 ⁇ m, and the useful, fine portion ⁇ 32 ⁇ m decreases only slightly from 99.0% to 98.6%.
- the luster pigments of the invention are advantageous for many applications, in particular for coloring paints, printing inks and plastics.
- Iron oxide-coated aluminum pigments are prepared using a two-shell, oil-heated stainless steel fluidized bed reactor built from 3 parts:
- a middle, cylindrical part having a diameter of 30 cm and a height of 1.5 m;
- each pigment sample was incorporated into 96 g of a polyester varnish having a solids content of 21% by weight (adjusted to an efflux time of 35 sec from DIN cup 4 by diluting with butyl acetate) by dispersing for 15 min with a propeller stirrer (IKA-Ruhrwerk from Janke und Kunkel) at 1500 rpm.
- a propeller stirrer IKA-Ruhrtechnik from Janke und Kunkel
- the pigmented varnishes were then applied with an electrically driven film applicator (from Braive Instruments) to the coated side of a white Chromolux card (700/350 g, size 30 ⁇ 45 cm) at a rate of 10 mm/sec using a 200 ⁇ m box drawbar (from Erichsen, Type 335, width 25.5 cm). Following a flash-off time of 20 min at room temperature, the film was again drawn down to 200 ⁇ m and flashed off for another 20 min. The card was then baked at 90° C. for 30 min.
- an electrically driven film applicator from Braive Instruments
- the CIELAB values were measured in the drawing direction on the middle part of the drawdown using a DATACOLOR spectro-photometer MSC 111 with a metallic measuring head GK 111 at an angle of from 20° to 70° to the luster angle.
- the reported lightness L, hue angle H* and chroma C* relate to the standard illuminant D65 and a viewing angle of 25°, 45° and 70°.
- a sample of the aluminum pigment thus treated had a carbon content of 0.07% by weight.
- Vaporized iron pentacarbonyl in 850 l/h carrier gas stream of nitrogen was then additionally introduced via the carbonyl nozzle at arate of 600 g/h. After 6000 g of Fe(CO) 5 had been introduced, the supply of carbonyl, air and water vapor was discontinued.
- Example 1 was repeated on 8 kg of the aluminum pigment without pretreatment. It was coated directly with iron oxide until a golden hue was obtained. This required 5500 g of Fe(CO) 5 .
- the yield was 10.06 kg of golden-colored Fe 2 O 3 -coated aluminum pigment having an iron content of 15.3% by weight and a carbon content of 0.25% by weight (the yield being 92.2% of theory).
- the pigment had a screen yield ⁇ 32 ⁇ m of only 65%. Examination under an optical microscope revealed that 5% of the metal flakes had not been coated, since they had a silvery color.
- the coloristic data of the pigment are listed in the following table:
